Pickard-Cambridge 1885	<div><p>Dysdera cylindrica group</p> <p>The cylindrica group, sensu Charitonov (1956: 19).</p> <p>Note. Deeleman-Reinhold &amp; Deeleman (1988) assigned all Dysdera species to nine species groups: aculeata, asiatica, crocota, erythrina, festai, lata, longirostris, ninnii and punctata. D. cylindrica O. Pickard-Cambridge, 1885, together with D. arnoldii Charitonov, 1956 and D. subcylindrica Charitonov, 1956 were placed in the asiatica group comprising of 18 species that are distributed from the eastern Mediterranean to Central Asia. Almost all these spe- cies are restricted to the Balkans and Anatolia (Deeleman-Reinhold &amp; Deeleman 1988). Yet, the known range of the asiatica group is strongly disjunct, because its representatives are unknown from the area between Syria and Uzbekistan. It is likely that such disjunction is simply caused by the lack of data from Iraq and Iran. Earlier, Chari- tonov (1956) assigned three Central Asian species, D. arnoldii, D. cylindrica and D. subcylindrica to a separate cylindrica group. These species are similar to each other, occur in the same region and, in our opinion, could represent a monophyletic grouping. Therefore, in the present paper, we follow Charitonov (1956) and consider three Central Asian species in the cylindrica group, which could or could not be part of the asiatica group. The latter matter can be decided when more Dysdera species have been recorded/described from Iraq and Iran.</p> <p>Diagnosis. The group can be distinguished by legs having a reduced spination and shortened tarsi, as well as by the flat carapace (Charitonov 1956). Males of the representatives of this group are characterized by the tegulum and the psembolus being equal in length, the triangular posterior apophysis (Ap) and the psembolus being equipped with a strong spine on its retrolateral side (Marusik 2017).</p> <p>Composition. Three species are included, all share the aforementioned diagnostic characters: D. arnoldii Charitonov, 1956 (Central Asia), D. cylindrica O. Pickard-Cambridge, 1885 (Pakistan) and D. subcylindrica Charitonov, 1956 (Central Asia).</p> <p>Comments. Species of the cylindrica group are restricted to Central Asia: Kazakhstan, Kyrgyzstan, northern Pakistan, Tajikistan and Uzbekistan.</p> </div>	https://treatment.plazi.org/id/895C87A9E109AF08FF0C3C24FD82F84F	Public Domain	No known copyright restrictions apply.

Dysdera subcylindrica is closely related to D. arnoldii and D. cylindrica. It differs from D. cylindrica in a number of characters: relatively short legs (femur I/carapace ratio 0.93 in male and 0.84 in female, compared to 1.05 and 0.96, respectively), distal part of the psembolus with a less developed crest (C), and the spermatheca (St) without a distinct stalk. Besides, D. subcylindrica can be separated from D. arnoldii by larger size: the carapace length is 4.15–4.35 in both sexes, compared to 3.5 in the male and 3.7 in the female in D. arnoldii. The same applies to the bulb length, which is 1.3 in D. subcylindrica and only 1.1 in D. arnoldii. The male of D. subcylindrica differs from that of D. arnoldii in having the tegulum (Te) with parallel edges in posterior view (convex in D. arnoldii) and the psembolus with a blunt tip (pointed in D. arnoldii). Endogynes of both species are almost indistinguishable, but that of D. subcylindica possesses a triangular dorsal arch of the diverticulum (Dd), compared to a trapezoidal dorsal arch in D. arnoldii.</p> <p>Description. Male. Total length 8.6. Carapace: 4.25 long, 3.2 wide. Abdomen: 4.5 long, 2.35 wide. AME 0.23, PME 0.16, PLE 0.17. General appearance as in Figs 1, 7–9. Carapace and chelicerae red.

IV: Fe d4; Ti p3 r2 v9; Mt p7 r3 v3. Endogyne as in Figs 50–51. Spermatheca wide, 4.5 times wider than long. Lateral arms (La) inclined posteriorly. Transverse bar of the posterior diverticulum (Tb) bulging anteriorly. Posterior diverticulum (Pd) in the shape of an inverted triangle.</p> <p>Size variations. Males vary from 8.6 to 10.4 in body length, carapace 4.15–4.35 long, 3.2 wide (n=3). Females vary from 9.9 to 10.6 in body length, carapace 4.15–4.35 long, 3.0–3.2 wide (n=3).</p> <p>Distribution. The species is known from the Hissar Mts in Tajikistan throughout the Alay Range in Kyrgyzstan to the Trans-Ili Alatau Mts in Kazakhstan. Dunin (1985) recorded D. arnoldii from eastern Uzbekistan and northern, western and central Tian Shan. However, some of his records could actually belong to D. subcylindrica, since he mistakenly considered the latter species a junior synonym of D. arnoldii.</p> <p>Comments. The original descriptions of D. subcylindrica and D. arnoldii are in Russian and provided with sketchy drawings of the bulb shown in posterior view, while their endogynes were not illustrated (figs 4 and 5 in Charitonov 1956). Dunin (1985), based on the materials available to him, came to the conclusion that D. subcylindrica was described based on large specimens of D. arnoldii and hence was to be treated as a junior synonym of the latter. This synonymy was rejected by Deeleman-Reinhold &amp; Deeleman (1988), who provided the first illustration of the endogyne of D. arnoldii. Having studied the bulbs of newly collected specimens of Dysdera from the Trans- Ili Alatau Mts, we have concluded that they do belong to a species from the cylindrica species group. A comparison of our specimens with the syntype male of D. arnoldii has revealed differences in the shape and size of the bulbs, as well as in the body size. We have had no opportunity to re-examine males from the original type series of D. subcylindrica, since they were lost (S. L. Esyunin, personal comm.). A comparison of the endogynes of newly collected specimens from the Trans-Ili Alatau Mts with that of the syntype of D. subcylindrica have revealed no differences. In addition, our identification of recently collected specimens as D. subcylindrica is confirmed by their large size (carapace length 4.15–4.35, bulb length 1.3). Therefore, it is safe to assigny the newly collected Dysdera specimens to D. subcylindrica based on the following facts: (1) the bulb conformation of our specimens is identical to that given in the original description; (2) the structural identity of endogynes between newly collected specimens and the syntype of D. subcylindrica; and (3) large body and bulb sizes in our specimens (larger than those in D. arnoldii).</p> </div>	https://treatment.plazi.org/id/895C87A9E10AAF0EFF0C38C8FA3CF8BB	Public Domain	No known copyright restrictions apply.

The new species is similar to D. brignolii, D. kugitangica and D. nenilini in having the strongly prominent semi-oval median crest (Cm) and similar proportions of the bulb: viz., the psembolus 1.2–1.6 times lon- ger than tegulum (Te). The male of D. mikhailovi sp. nov. can be separated from that of D. brignolii by the psembolus stem (Se) being two times thinner than the tegulum (equal in D. brignolii) and the median crest length/height ratio 3.3 (2.3 in D. brignolii). The male of the new species can be distinguished from that of D. kugitangica by the rounded proximal part of the median crest and the retrolateral crest (Cr) divided into two lobes (solid in D. kugitangica). From D. nenilini the male can be distinguished by the rounded distal part of the median crest (pointed in D. nenilini) and the curved bulb, forming an angle of 130° between the tegulum and the psembolus (tegulum and psem- bolus stretched out in almost a straight line in D. nenilini). The female of D. mikhailovi sp. nov. can be separated from that of D. kugitangica by the absence of the spermatheca stalk; from that of D. nenilini it differs in having the rectangular rather than triangular spermatheca (St). The female of D. brignolii is yet unknown.</p> <p>Description. Male. Total length 5.7. Carapace: 2.85 long, 2.05 wide. Abdomen: 2.95 long, 1.55 wide. AME 0.14, PME 0.11, PLE 0.11.

Carapace and chelicerae red. Sternum, labium and maxillae orange. Palps yellow-orange. Legs: I and II yellow-orange, III and IV yellow. Abdomen and spinnerets beige. Leg measurements: 3.75, 2.35, 3.25, 3.0, 0.65 (13.0). II: 3.55, 2.2, 3.05, 2.95, 0.65 (12.4). III: 2.9, 1.65, 2.0, 2.65, 0.6 (9.8). IV: 3.75, 2.0, 3.0, 3.6, 0.7 (13.05). Leg spination: III: Ti p4 r2 v3; Mt p6 r2 v3. IV: Fe d2; Ti p4 r2 v6; Mt p5 r3 v5. Endogyne as in Figs 54–55. Spermatheca rectangular, 3.4 times as wide as long. Dorsal arch of the diverticulum (Dd) low partially overlaps by spermatheca. Transverse bar of posterior diverticulum (Tb) pentagonal, 1.3 times wider than spermatheca. Posterior diverticulum (Pd) with two peaks.</p> <p>Size variations. Females vary from 10.8 to 11.0 in body length, carapace 4.6–4.7 long, 3.35–3.45 wide (n=2).</p> <p>Distribution. Known only from the type locality (Figs 58–59).</p> <p>Comments. Due to big differences in body sizes, there are doubts whether the holotype male is correctly matched with the paratype females. The carapace length in the female is 1.5 times longer than that in the male. Nonetheless, they were collected together and therefore were provisionally accepted as belonging to the same spe- cies.</p></div> 	https://treatment.plazi.org/id/895C87A9E104AF07FF0C3E96FF66F9E9	Public Domain	No known copyright restrictions apply.
